Orientation adjusting stereo audio output system and method for electrical devices


Arrangements described herein relate to systems and methods for adjusting the audio output from an electrical device based on the orientation of the device to provide proper stereo audio output for more than one orientation of the device. The audio output system includes at least two speakers. The device includes an orientation sensor, which can be accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. The audio output system can be operatively connected to the orientation sensor. Based on orientation data collected by the orientation sensor, output from the audio output system can be adjusted to provide audio output from opposing left and right regions of the device. Such adjustments can be implemented by the orientation sensor itself or by a switching device (such as a processor, digital logic gate or switching transistor) operatively positioned between the orientation sensor and the audio output system.

FIELD

Embodiments relate in general to electrical devices and, more particularly, to electrical devices that provide stereo audio output.

BACKGROUND

Some portable electrical devices, such as smart phones and tablet computers, are configured to provide stereo audio output. Stereo audio output is achieved by providing two speakers in opposite regions of the device. For instance, these two speakers are usually positioned on the left and right sides of the device or along the left and right ends of one edge of the device.

Some application software programs being executed on such electrical devices may generate video output that is best suited to a specific device orientation. For example, some games are designed for a portrait aspect ratio, while some others are best viewed in a landscape mode. However, tilting the device at a 90 degree angle can change the orientation of the speakers provided on the device. Thus, instead of providing audio from the left and the right, as intended, the speakers (and the sound emitted therefrom) may now be from the top and bottom of the device, destroying the left/right separation of audio channels. As a result, a user\'s enjoyment of the audio aspects of the device may be diminished.

Moreover, some portable electrical devices, like tablet computers and cell phones, contain orientation sensors and allow the visual output of applications and media to be presented properly regardless of the device\'s orientation. For example, a video can be displayed on the portable electrical device. The device can be placed into one of four possible orientations. A user can watch video on the device when the device is in any of four orientations because the orientation sensor ensures that the video is presented in the proper orientation. However, with a conventional two-speaker device, proper stereo output is provided in only one of these orientations.

Thus, there is a need for a system and method that can minimize such concerns.

SUMMARY

In one respect, embodiments relate to an electrical device having an audio output system and an orientation sensor. The electrical device can be a cellular telephone, a smart phone, a personal digital assistant, a tablet computer, a laptop computer, a digital reader, a portable electrical device, a portable computing device, an entertainment device, a global positioning system device, a digital audio player, an e-book reader, a camera or a game console.

The audio output system includes two or more speakers. In one embodiment, one speaker can be located within a first region of the electrical device, and a second speaker can be located within a second region of the electrical device. The first region can be opposite the second region. In one embodiment, the audio output system can include three speakers.

The orientation sensor is configured to collect data regarding the orientation of the electrical device. The data regarding the orientation of the electrical device is used to adjust the output from the audio output system. In this way, stereo audio output can be provided for a plurality of orientations of the electrical device. In one embodiment, stereo audio output can be provided from opposing left and right regions of the electrical device for at least two different orientations of the electrical device.

The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, a pressure sensor to detect the points at which the electrical device is being supported or combinations thereof. In one embodiment, the orientation sensor can be directly connected to the audio output system. In such case, the orientation sensor can be, for example, a mercury switch or a ball-bearing based position sensor. In another embodiment, the orientation sensor can be indirectly connected to the audio output system. In such case, a switching device can be operatively positioned between the orientation sensor and the audio output system. As an example, the switching device can be a processor. The processor can be configured to: determine the orientation of the electrical device based on orientation data collected by the orientation sensor, and adjust output from the audio output system based on the determined orientation. As another example, the switching device can be a switching transistor. As yet another example, the switching device can be a digital logic gate.

In another respect, embodiments are directed to an orientation adjusting stereo output method for an electrical device. The device has an audio output system including at least two speakers.

According to the method, data regarding the orientation of the electrical device is collected. The output from the audio output system is adjusted based on the data collected regarding the orientation of the electrical device. As a result, stereo audio output can be provided for a plurality of orientations of the electrical device. The method can further include determining whether the orientation of the electrical device has changed. If the orientation of the electrical device has changed, the audio output from the audio output system can be adjusted such that stereo audio output is provided from the electrical device to accommodate the new orientation.

In one embodiment, the adjusting can be performed by an orientation sensor. The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, a pressure sensor to detect the points at which the electrical device is being supported, or combinations thereof. In another embodiment, the adjusting can be performed by a switching device operatively positioned between the orientation sensor and the audio output system. The switching device can be a processor, a switching transistor or a digital logic gate.

In one embodiment, the audio output system can have three speakers. In such case, the adjusting can include selecting at least two of the three speakers based on the determined orientation of the electrical device such that the selected speakers provide stereo audio output from the electrical device. Audio data can be output from the selected speakers.

In still another respect, embodiments are directed to an electrical device. The electrical device can be a cellular telephone, a smart phone, a personal digital assistant, a tablet computer, a laptop computer, a digital reader, a portable electrical device, a portable computing device, an entertainment device, a global positioning system device, a digital audio player, an e-book reader, a camera or a game console.

The electrical device includes an audio output system, which has at least three speakers: a first speaker, a second speaker and a third speaker. The device also includes an orientation sensor that is configured to collect data regarding the orientation of the electrical device. In one embodiment, the orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. Alternatively or in addition, the orientation sensor can be a pressure sensor to detect the points at which the electrical device is being supported.

Further, the device includes a processor that is operatively connected to the audio output system as well as to the orientation sensor. The processor is configured to (a) determine the orientation of the electrical device based on orientation data collected by the orientation sensor; (b) select at least two of the speakers based on the determined orientation of the electrical device; and (c) output audio data to the selected speakers. Thus, stereo audio output can be provided regardless of the orientation of the electrical device. The stereo audio output can be provided from opposing left and right regions of the electrical device.

The processor can be further configured to determine whether the orientation of the electrical device has changed based on orientation data collected by the orientation sensor. If the orientation of the electrical device has changed, the audio output from the audio output system can be adjusted such that stereo audio output is provided from the electrical device to accommodate the new orientation.

In one embodiment, the first speaker can be located within a first region of the electrical device. The second speaker being located within a second region of the electrical device. The first region can be opposite the second region. The third speaker can be located in the first region or in the second region of the device.

In yet another respect, embodiments are directed to an orientation adjusting stereo output method for an electrical device. The device has a processor, at least three speakers, and an orientation sensor. The processor is operatively connected to the at least three speakers as well as to the orientation sensor. The orientation sensor can be an accelerometer, a gravity sensor, a gyroscope, a tilt sensor, an electronic compass, or combinations thereof. Alternatively or in addition, the orientation sensor can be a pressure sensor to detect the points at which the electrical device is being supported.

According to the method, the orientation of the electrical device is determined based on orientation data collected by the orientation sensor. At least two of the three speakers are selected based on the determined orientation of the electrical device. The selected speakers can be on opposing left and right regions of the electrical device. Such selection can include selecting speakers that are located on opposing right and left regions of the electrical device. Audio data is output to the selected speakers. Thus, stereo audio output is provided regardless of the orientation of the device.

The method can also include determining whether the orientation of the electrical device has changed based on orientation data collected by the orientation sensor. If the orientation of the electrical device has changed, at least two of the three speakers can be selected based on the determined orientation of the electrical device to accommodate the new orientation. Thus, stereo audio output can be provided regardless of the orientation of the device.
